Find roots of polynomial $$ p(x) = 3x^4-5x^2+2x-1 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 1.1574\\[1 em]x_2 &= -1.5027\\[1 em]x_3 &= 0.1726+0.4023i\\[1 em]x_4 &= 0.1726-0.4023i \end{aligned} $$Explanation
Polynomial $ 3x^4-5x^2+2x-1 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
